If tips are pooled they're split evenly or based on a points system determined by your position. So it's generally fair.
Some states pay a super low hospitality minimum wage that is made up for with tips. Others like California don't. Either way, unless you have a great job in hospitality (generally server or bartender in a busy place or place with great regulars) you can't live a good life on the proceeds, especially in California and other large states and cities.
I'm so used to this model. But I think the European model can make more sense. And tipping seems to be increasing there. I have actually come across tip screens in more modern coffee shops in Spain and France.
I appreciate the thoughts.
